The present invention relates to a jack and has for its prime object toprovide a structure whereby the lifting element of the jack may beactuated upwardly by one stroke of a lever. Another very importantobject of the invention resides in the provision of a jack of thisnature whichis exceedingly simple in its construction, inexpensive tomanufacture,

strong and durable, thoroughly efiicient and w reliable in use, andoperation, easy to manipulate, and otherwise well adapted to the purposefor which it is intended.

With the above and numerous other objects in view as will appear as thedescriptionpro- 59' ceeds, the invention resides in certain novelfeatures of construction, and in the combina tion and arrangment ofparts as will be hereinafter more fully described and claimed.

In the drawings Figure 1 is aside elevation ofa jack embodying thefeatures of my invention,

Figure2 is a sectional view therethrough taken horizontally on the line2+2. of Fig ure 1,

Figure 3 is a vertical section through the jack, v V Figure 4 is an endelevation thereof, Figure 5 is horizontal section taken substantially onthe linev 55 of Figure 3,'and Figure 6 is a perspective view of thecatch. Referring to the drawings in detail it will be seen that thenumeral 5 denotes a base with a standard 6 rising therefrom and N formedwith a vertical bore 7 leading from the top end thereof and terminatingin a vertical slot 8 in the lower portion of the standard. A shank 9 isslidable through the bore 7 and has a head 10 on the upper end [athereof and its lower end is bifurcated and between the furcations 11there is journalled a pulley 12. A lever L comprises a pair of sidemembers 14: pivotally mounted inter mediate their ends as at 15 on thesides of a: the standard 6 and adjacent ends project inwardly towardeachcother as at 17 and are engaged by suitable means 18 with a cable 19which is trained under the pulley l2 and over a pulley 20 in a bracket21 at the top of the standard'and anchored as at 22 to a handle bar 23fixed between sleeve segment extensions 24 on the other ends of the arms14. It will therefore be seen that when the handle 23 is swungdownwardly the cable is drawn over the pulley 20 and under the pulley 12thereby raising the shank 9 and in order to hold the shank and its head10 in a raised position I provide a catch 26 pivotally mounted as at 27on the standard 6 alongside of the slot 8 for engagement with one of theside arms 14 and this catch is held in engag-co ing position by meansofa spring 28 which holds the lateral stop 29 in engagement with thestandard. I

It is thought that the construction, operation, utility and advantagesof this invention fis will now be quite apparent to those skilled inthis art without a'more detailed description thereof.

, The present embodimentof the invention has been disclosed inconsiderable detail mere ly for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention-and the above description;It will be apparent that changes in the details of construction, and inthecombination and arrangement of parts may be resorted to withoutdeparting from thespirit or scope of I the inve'ntionas'hereinafterclaimed or sacrigu ficing any of its advantages. I

Having thusdescribed my invention, what I claim as new is:

1. A jack of the class described comprising a standard, a shank slidablelongitudinally through the standard, a pulley on the inner end of theshank, a lever rockably mounted on the standard, a cable anchored to thelever at spaced points one to each side of the standard'and trainedunder the pulley, a second pulley on the standard adjacent one endthereof over which said cable is trained.

2.. A jack of the class described comprising a standard, a shankslidable longitudinally through the standard, apulley on the inner endof the shank, a lever rockably mounted on the standard, a cable anchoredto the lever at spaced points one to each side of the standard andtrained under the pulley,a second pulley on the standard adjacent l oneend thereof over Which said cable is trained, said lever including apair of arms one on each side of the standard and pivoted thereto.

5 3. A jack of the class described comprising a standard, a shankslidable longitudinally through the standard, a pulley on the inner endof the shank, a lever rockably' mounted on the standard, a cableanchored to the lever at spaced points one to each side of the standardand trained under the pulley, a second pulley on the standard adjacentone end thereof over which said cable is trained, said lever including apair of arms one on each V side of the standard and pivoted thereto,ad-

jacent ends of the arms projecting inward- 1y to which one end of thecable is anchored,

a handle bar between the other ends of the arms and the other end of thecablebeing anchored to the inner end of said bar.

4. A jack of the class described comprising a standard, a shank slidablelongitudinally through the standard, a pulley on the inner end of theshank, a lever rockably mounted on the standard, a cable anchored to thelever at spaced points one to each side of the standard and trainedunder the pulley, a second pulley on the standard adjacent one endthereof over which said cable is .30 trained, said lever including apair of arms one on each side of the standard and pivoted thereto,adjacent ends of the arms projecting inwardly to which one end of thecable is anchored, a handle bar between theot-her ends of the arms andthe other end of the cable being anchored to the inner end of said bar,a catch pivotally mounted on the standard to engage one of the arms forholding the shank in a raised position.

5. A jack of the class described comprising a standard, a shank slidablelongitudinally through the standard, a pulley on the inner end of theshank, a lever rockably mounted on the standard, a cable anchored to thelever at spaced points one to each side of the standard and trainedunder the pulley a second pulley on the standard adjacent one endthereof over which said cable is trained, said lever including a pair ofarms one on each side of the standard and pivoted thereto, ad-

jacent ends of the arms projecting inwardly to which one end, of thecable is anchored, a handle bar between the other ends of the arms andthe other end of the cable being anchored to the inner end of said bar,a catch pivotally mounted on the standard to engage one of the arms forholding the shank in a raised position, the shank being bifurcated andsaid first pulley being journalled between the furcations thereof.

In testimony whereof I aflix my signature.
